Welker - Model GSS-4PM -Natural Gas Composite Samplers
The Welker GSS-4PM Composite Gas Sampler extracts a sample from the flowing product in the pipeline and uses positive displacement to capture a representative sample.
Location Matters
Center One-Third
Placing the sample probe in the center 1/3 of the pipeline is a significant factor in gathering a representative sample. Avoid placing the sampler in turbulent spots such as pipe elbows and traps. We can help you find the best installation point for your sampler. We can even install it for you. Just give us a call.
